A socket can get fin and a state will be changed on CLOSE_WAIT, which is not supported yet. Signed-off-by:

We have a window between getting info about tcp connections and blocking them. #2419 v2: clean upV v3: don't update lengthes of queues for listen sockets, they don't used. v4: check that a state of a tcp connection is ESTABLISHED or CLOSE v5: * don't check state, because it can be changed only on TCP_CLOSE. In this case it will be changed again after restoring. * refresh a socket after enabling the repair mode Signed-off-by:

- use pthread_sigmask instead of sigprocmask - show_sigset should take the size of dereferenced variable - zeroify sigsets before use, since libc has own definition for sigset which doesn't match one the kernel uses http://bugzilla.openvz.org/show_bug.cgi?id=2437Signed-off-by:

Same as previous patch -- easier to read and possible to use tags. Signed-off-by: -
Pavel Emelyanov authored
This makes code more readable, saves one ptr on stack and lets us jump into restorer code using tags. Signed-off-by:

To test threads blocked signals restoration. Signed-off-by:

Cyrill Gorcunov authored
To unify the code for both thread leader and regular threads we move blocked signals for thread leader into threads argument area and use restore_thread_common() helper. Signed-off-by:

I've moved dump_thread helper a bit lower in file since I've to call for find_thread_state helper. After all this groups all thread related functions in one slab. Signed-off-by:

This patch starts using parasite_init_threads_seized and parasite_fini_threads_seized helpers to save per-thread data in parasite and remove it on cure procedure. Signed-off-by:

We will need to extend the structure to keep not only tid/tid_addr but blocked signals as well, thus rename it to more generic parasite_dump_thread. The command PARASITE_CMD_DUMP_TID_ADDR renamed to PARASITE_CMD_DUMP_THREAD for the same sake. Signed-off-by:

We will use them from crtools code to save and restore blocked signals mask of threads. Signed-off-by:
-
Cyrill Gorcunov authored
- the init() now calls for init_thread() to save blocked signals mask in per-thread data - the fini() now calls for fini_thread() to restore the blocked signals, note: we could use thread_leader directly but i think calling for fini_thread() is more generic - dump_misc() now uses per-thread data Signed-off-by:

These helpers will be needed to save a blocked signals mask for dumpee threads. Signed-off-by:

Cyrill Gorcunov authored
The per-thread information requires own space in parasite data. In particular we will keep the blocked signals bound to thread pids. For this sake the caller need to provide the parasite how many threads will be used to calculate space. Signed-off-by:

Linux kernel emulates anon-shared mappings by mapping internal tmpfs file in. We try to detect this by checking that the file under map is such, but do it with error -- major == 0 check is wrong, as regular tmpfs file can be such as well as btrfs or ecryptfs can screw things up. The only working way of doing this is to get the dev_t of this internal tmpfs mount. Signed-off-by: -
